An electromagnetic clutch includes a first rotatable member for connection to an external driving source and a second rotatable member for connection to a driven member. An annular magnetic member is connected to the second rotatable member through a plurality of leaf springs. A third rotatable member is connected to the second rotatable member to limit the axial movement of the annular magnetic member. A plurality of connecting and absorbing devices are fixedly disposed between the annular magnetic member and the third rotatable member. These devices absorb vibration and impact forces when the annular magnetic member is attracted to the first rotatable member. A device is provided for preventing the destruction of the connecting and absorbing device due to the impact force and vibration created upon engagement of the electromagnetic clutch.
